Dynamics of a single model neuron ∗

The parametrized dynamics of a standard nonlinear model neuron with self-interaction is discussed. For units with a self-excitatory connection a hysteresis effect is observed, and the underlying mechanism is identified as that of a cusp catastrophe. This is true for discrete as well as for continuous dynamics. For the discrete dynamics of self-inhibiting units there appear period-doubling bifur...

Versatile biologically inspired electronic neuron.

We present a biologically inspired electronic neuron based on a conductance model. The channels are constructed using linearly voltage controlled field effect transistors. A two channel and a three channel circuit is developed. The dynamical behavior of this system is studied, showing for the two channel circuit either class-I or class-II excitability and for the three channel circuit bursting ...

Delayed Random Walk Model of Single Neuron

We propose a delayed random walk model of stochastic single neuron which has a delayed self{exciting feedback. Using computer simulation the model is studied to examine how the delay in the self{excitation aaects the bistable stochastic dynamics of the model neuron. It is found that progressive delay causes the width of two bimodal peaks of the stationary probability distribution to increase, a...

Ventral Neurogenesis and the Neuron-Glial Switch

In the developing spinal cord, neuroepithelial precursors at different positions along the dorsal-ventral axis generate distinct neuronal and glial subtypes. For example, one group of ventral precursors generates neurons followed by oligodendrocytes. A spate of recent articles, including several in this issue of Neuron, are devoted to the mechanisms governing neuronal and glial subtype specific...
